Emerson 1C31116G04 is an analog input module in the Ovation system, mainly used for cold junction compensation (CJC) of thermocouple signals. It measures the temperature of the terminal block through a built-in temperature sensor, and calculates the actual temperature by combining with the thermocouple voltage signal to solve the measurement error caused by the temperature change of the reference end. The module needs to be used in conjunction with the terminal block cover (1C31207H01) to maintain uniform temperature in the terminal block and sensor area.

Compatibility Scenarios

Compatible Electronics Modules

1C31116G04 works with electronics modules 1C31113G01, 1C31113G02, and 1C31113G03 to form a 13-bit Analog Input Module. The voltage input ranges provided by the electronics modules are:

1C31113G01: ±20mV

1C31113G02: ±50mV

1C31113G03: ±100mV

Application Scenarios

Suitable for industrial process control scenarios requiring thermocouple temperature measurement, such as high-temperature equipment monitoring and furnace temperature control. The module supports 8 channels of thermocouple signal input, with the 9th channel dedicated to cold junction compensation logic (no physical device connection).

Wiring and Installation Requirements

Terminal Block Connections

Thermocouple Inputs: Connect the positive poles of thermocouples to A1+~A8+, negative poles to A1-~A8-, and shield layers to SH1~SH8.In non-CE systems, ground the shield layers; in CE systems, do not connect the shields to ground.

Temperature Sensor: The built-in sensor requires no additional wiring, as cold junction compensation is implemented via internal circuitry of the module.

Grounding and Shielding

Shielded Cables: Ground shielded cables at a single point (preferably at the signal source). In CE-certified systems, ground the shield at the cabinet entry point.

Interference Prevention: Avoid sharing the same shield layer with high-level signals to prevent electromagnetic interference.

Jumper Configuration

Local Grounding/Field Grounding: Set via internal jumpers of the module:Default: Local grounding (jumpers installed vertically).

Field grounding: Remove jumpers.

Operation Precautions: Accessing jumpers requires opening the module casing; follow ESD (electrostatic discharge) protection protocols.
